Otosclerosis: audiometric results and quality of life after stapedectomy with interposition or CO₂ laser-calibrated stapedotomy without interposition

Abstract

Background

The surgical treatment of otosclerosis consists of the replacement of the stapes using a piston.

Aims/Objectives

The objective of this study is to assess the audiometric results and quality of life (QOL) of patients who underwent surgery for otosclerosis by stapedectomy with fascia interposition (STIP) or by stapedotomy using CO₂ laser (SLaser) without fascia interposition.

Material and Methods

Ninety-one patients operated on for otosclerosis by STIP (40 patients) and by SLaser (51 patients) were included. Audiometric results were graphically displayed using the Amsterdam Hearing Evaluation Plot and were compared to the Common Otology Database (COD) comprising 660 patients. The patients’ QOL was assessed with an otological validated survey. The significance level was p < .05.

Results

There was no significant difference in hearing improvement between SLaser and STIP-operated patients. There was no significant difference between our results and that of COD. QOL was significantly improved (+3.5/10) postoperatively for both STIP and SLaser in both social and professional fields.

Conclusions and Significance

By comparing QOL and hearing gain of STIP and SLaser, our results suggest that both surgical techniques are a safe and successful treatment for otosclerotic stapes fixation. Further studies aiming at comparing larger series may confirm and refine these results.

Chinese Abstract

背景：耳硬化症的手术治疗包括使用耳钉置换镫骨。

目的：本研究的目的是评估通过筋膜介入镫骨切除术接受耳硬化症手术 (STIP) 或在没有筋膜介入的情况下使用 CO2 激光 (SLaser) 进行镫骨切开术的患者的听力结果和生活质量(QOL)。

材料和方法：纳入91 名接受耳硬化症手术的患者, 包括 STIP（40 名患者）和SLaser（51 名患者）。 听力测试结果通过阿姆斯特丹听力评估图显示, 并与由660 名患者组成的通用耳科数据库 (COD) 进行比较。 通过耳科验证调查评估患者的生活质量。 显著性水平为 p < .05。

结果：SLaser 和 STIP 手术患者的听力改善之间没有显著差异。 我们的结果与 COD 的结果没有显著差异。STIP 和 SLaser的术后 QOL, 在社交和专业方面, 均得到显著改善 (+3.5/10)。

结论和意义：通过比较 STIP 和 SLaser 的 QOL 和听力增益, 我们的结果表明这两种手术技术都是安全且成功的治疗耳硬化镫骨固定的方法。进一步研究, 对更大系列进行比较, 可能会证实和完善这些结果。
